Question

The width of David's tent is 5 feet the length is twice the width Davids air mattress measures 3 feet by 6 feet how many square feet of floor space will be available for the rest of his things

Answer 1

If the length is twice the width, means length is :
`2\quad * \quad 5\quad =\quad 10`
To find the area multiply the width and length :
`10\quad * \quad 5\quad =\quad 50` . The air mattress' area is
`3\quad * \quad 6\quad =\quad 18` We should substract the air matress' field from the tent's :
`50\quad -\quad 18\quad =\quad 32` The answer is 32 square feet.
